CHICAGO — Prosecutors have described Kevin Trudeau as an "uncontrollable huckster" in urging a federal judge to imprison the TV pitchman for at least 10 years for bilking consumers through widely aired infomercials.

In a court filing in Chicago this week, they blast Trudeau as "an unrepentant, untiring and uncontrollable huckster." They add the 50-year-old is even likely to cheat fellow inmates. Sentencing is March 17.
